We're going to go on our systematic approach to diagnosing a pool heater by hunting at what to do visit us if the gentle in the control pad to the top rated within your Sta-Rite pool and spa heater that may be labeled “service heater” is lit. (We are going to progress along with the assumption that you know almost everything from phase 1.) This time you must remove the sides from the heater ahead of disconnecting electrical power for the heater so that you can go through the codes around the board attached towards the topside. Right after eliminating the sides, you will notice the big topside that is definitely nonetheless connected to the heater. Down below the topside is often a metal panel that retains the topside in position. Underneath this panel you'll find two locking pins (cotter pins). Diligently clear away the 2 pins and retail store them somewhere risk-free right up until reassembly. Carefully clear away the very best and switch it upside down. You will see a light-weight lit within the board you might be on the lookout at if you switch the topside about. The sunshine will be close to a code that is created over the board.

The 1st code that you'll see around the left facet of your board might be PS. This is the code for your force switch. We coated the pressure change in phase a person. If this mild is lit go back to phase a single and evaluate that phase. If required stick to the instructions to replace the tension swap.

The following code you can expect to see around the board is HLS. When you use a controller on the procedure you will have to bypass it at the moment. You need to meticulously disconnect the ability through the heater. After you are positive the energy is disconnected, you have got to uncover and open the high-voltage cupboard. This cabinet is often a steel box in the midst of the heater. If you're looking at the cupboard, there may be ordinarily a screw on the top rated right facet. Loosen the screw along with the door will swing down toward you. You will need to get extremely watchful when doing work in this particular box and only accomplish that once you are sure which the electricity for the heater is OFF.

You must bypass the firewall safety interface. To accomplish this you'll have to have a shorter wire with stab-tab connectors. Should you have a controller and it absolutely was effectively mounted the wire can have been remaining while in the box through the tech who set up the controller. Otherwise you need to make this jumper wire. At this time seem in your owner's manual to track down the two appropriate pins to connect with. Should you possess a controller or are working with a fireman's swap this is where your command needs to be linked. For those who use a controller and it truly is not connected here, it may be the source of one's troubles and either have a very certified tech proper the problem or right it by yourself.

You will need to watch out not to put the jumper wire about the electricity terminals or you will ruin your heater by burning up the digital system. Make use of your guide to find the place the fireman's change is meant for being connected and punctiliously attach your jumper involving these terminals. In case you now activate the ability as well as the heater will work with no problems, your issue lies in the controller or perhaps the wiring visiting the controller. You need to difficulty shoot this technique.

In the event you nonetheless have the very same issue with your heater. (“service heater” light arrives on), go away the jumper in position and confirm which the pump is on which you've good drinking water circulation. Be sure again with the meter which the stress switch is not really cycling. It need to study as a dead shorter. (See segment 1) With fantastic h2o movement verified along with the “service heater” light-weight on, your problem might be one of the thermo-regulators from the security process.
